Many physicians and other healthcare professionals have jobs at medical colleges and universities, and their job description include instruction and lecturing. In addition, many board certified physicians are working in university and teaching hospitals, and have the responsibility of teaching physicians in their residency training. Therefore, not only medical instructors working at medical schools and colleges need to learn about and practice instruction methods. Developing a doctor to be instructor in a university demands enrollment in a development course called "Instruction methods". Enabling board certified physicians to satisfactorily perform their role in teaching postgraduate and training of postgraduate physicians in their residency also requires providing them with the general principles of instruction. The development course described in this book aims at providing physicians with all the essential principles of instruction methods. This book is expected to be of interest to medical instructors, professors and physicians working in university and teaching hospitals.
